A computerized system provides assistance for placement of localization markers for medical operations such as ACL repair procedures. The system displays, on a graphical user interface, an image of an anatomical structure and allows identification, via an input device on the graphical user interface, of a set of landmark locations identifying respective anatomical positions within the displayed image of the anatomical structure. The system displays a graphical overlay over the image of the anatomical structure. Placement of the graphical overlay is based on the set of landmark locations. The system displays at least one localization marker within the graphical overlay. The localization marker(s) identify a location for performing a surgical operation associated with the anatomical structure, such as ACL repair surgical operations.

5. The method of claim 2 wherein displaying at least one localization marker comprises: receiving manual input from a medical professional, via an input device of the graphical user interface, to indicate a position within the overlay grid for placement of the localization marker based on a geometry of the overlay grid; and in response to the input from the medical professional, displaying a respective localization marker at each indicated position within the overlay grid.
6. The method of claim 1 wherein displaying an image showing a view of a femur and tibia within a human knee joint comprises: displaying a lateral view of the tibia within a human knee joint; wherein receiving a selection of first and second known bone locations comprises: receiving, as the first known bone location, a selection of an anterior edge of the view of the tibia displayed within the image; and receiving, as the second known bone location, a selection of a posterior edge of the view of the tibia displayed laterally within the image, a line defined between the first known bone location and the second known bone location defining a plane upon which the at least one localization marker can be displayed for repair of a ligament associated to the tibia.
7. The method of claim 6 wherein displaying a graphical overlay over the image of the anatomical structure comprises: displaying an overlay line between the select first and second known bone locations of the tibia; and wherein displaying at least one localization marker within the graphical overlay comprises: displaying at least one tibia localization marker located upon the overlay line, the at least one tibia localization marker identifying at least one anatomic ACL insertion site on the tibia displayed within the graphical user interface.
8. The method of claim 7 wherein displaying at least one tibia localization marker located upon the overlay line comprises: computing placement of the at least one tibia localization marker based upon placement of the at least one femoral localization marker previously positioned within a femur overlay grid, the femoral localization marker identifying a reference location for a tissue graft insertion site within a femur displayed within the graphical image.
9. The method of claim 1 comprising: based on placement of the at least one localization marker within the graphical overlay, computing placement of localization markers for at least one other anatomical structure, and displaying the localization markers for at least one other anatomical structure within the displayed image within the graphical user interface.
